Outdoor Reset
Enables the Outside Air Temperature sensor display and control logic.
No:
Outside Air Input (O+O-) is ignored.
Display Only: Do Not Calculate setpoint based on outdoor temperature,
Display Outside Air Temperature.
Outdoor Reset: Calculate the temperature setpoint based on outdoor
temperature using a reset curve defined by Outdoor Set Up,
Boiler Set Up, Outdoor Design and boiler Design
parameters.
Outdoor
Set Up
55
40 F to 100 F
The Outdoor Set Up temperature is the outdoor temperature at which the
Boiler Set Up temperature is supplied.
Only visible when Outdoor Sensor is set to Outdoor Reset .
Boiler
Set Up
140
80F to 180 F
The Boiler Set Up Temperature is the starting boiler water temperature of the
reset ratio. If the building feels cool during mild outdoor conditions, the
Boiler Set Up setting should be increased.
Only visible when Outdoor Sensor is set to Outdoor Reset.
Outdoor
Design
30
-20 F to 50 F
The Outdoor Design Temperature is the outdoor temperature at which the
Boiler Design temperature is supplied.
Only visible when Outdoor Sensor is set to Outdoor Reset.
Boiler
Design
180
80F to 220 F
The Boiler Design setting is the water temperature required to satisfy the
building heat loss during the Outdoor Design temperature. If the building feels
cool during cold outside conditions, the Boiler Design setting should be
increased.
Only visible when Outdoor Sensor is set to Outdoor Reset.
Blower
SPD
High
100
0 to 100 %
Percent of (0 - 10 vdc output (V+, V-) output that represents a 100%
modulation rate. This scaling factor allows the controller to display 100%
when the blower is at rated boiler output.
Blower
SPD
Low
0
0 to 100 %
Percent of (0 - 10 vdc output (V+, V-) output that represents a 0% modulation
rate. This scaling factor allows the controller to display 0% when the blower is
at minimum boiler output.
Low Fire
Spd
50
0 to 100 %
Modulation % used for Low Fire Hold and Low Fire Start conditions.

Description
0 to 100 %
Percent of blower operating range that the blower should be run during Fan
Purge (at ignition).
